[en] Systematics of heavy-ion-induced fission are reviewed. Rotation-induced nuclear deformation is shown to have little effect on most probable energies of evaporation α-particles. Comparative studies of neutron emission from Gd compound nuclei are continued, aiming to assess the influence of superdeformations on nuclear decay patterns. Measurements of mass and energy flow in damped reactions were analyzed in terms of a one-body transport model, predicting negligible correlations between bass asymmetry and excitation energy division. Monte Carlo simulations attribute reported correlations to experimental asymmetries. A measurement of neutrons emitted from correlated damped fragments from the ¹⁶⁵Ho+⁵⁶Fe reaction, employing a dual neutron multiplicity meter demonstrates non-equilibrium energy sharing in damped reactions. A simulation code for neutron emission in damped reactions was developed and an existing efficiency code was significantly modified for experiments with modular detectors and intermediate bombarding energies. Techniques of neutron multiplicity measurements at these energies are discussed. The multiplicity of non-equilibrium neutrons in damped ¹³⁹La+⁴⁰Ar reactions at 10 and 15 MeV/u was discovered to scale with the radial kinetic energy. A CAMAC event-handler module for neutron multiplicity meters was developed and used in experiments. A preliminary search for neutron production in a palladium/heavy-water electrolytic cell turned out negative
